Answer:
13=7+3h
Step-by-step explanation:
13 is all together, 7 for first week, and the other 3 have the same amount.
so you can say 13= 7 for the first week+ 3 of the same amount of hour which can be written as 3h.
If Candace made a scatter plot of the math scores of eighth-grade students (vertical scale) and their heights in inches (horizontal scale), what type of line of best fit should she expect the scatter plot show?
A. a line with positive slope
B. a line with negative slope
C. a horizontal line
D. There would be no line of best fit.
Answer:
The correct option is (D).
Step-by-step explanation:
A scatter plot is a mathematical graph used to display the linear relationship between two variables.
Points are plotted on the graph and a line of best is drawn to represent the linear relationship between the two variables.
If the line is upward moving this implies that there is positive relation between the variables.
If the line is downward moving this implies that there is negative relation between the variables.
If there is no line of best fit that can be formed using the data provided then this implies that there is no linear relationship between the variables.
The variables math-score and height of the students has no relation between them. This is because the height of a student does not factor the score he/she received in their math exam.
So, the scatter plot for this data will not have a line of best fit.
Thus, the correct option is (D).

Does every line have a slope and a y intercept?
Answer:
see below
Step-by-step explanation:
Not every line has a y intercept because vertical lines ( lines that go up and down) do not intersect the y axis
Does every line have slope? It depends on how you define slope
Vertical lines have a slope that is undefined. So they have a slope that is undefined. When you are asked what the slope of a vertical line is , you answer undefined
Answer:
no
Step-by-step explanation:
because the line can be 0

Angela and Tyler are selling tickets for a charity football game. Students will get a discount for the game. Angela sells 6 adult ticket and 10 student ticket for $122. Tyler sells 11 adult tickets and 5 student tickets for a total of $157. What is the of an adult ticket and what is the price of a student ticket?
A, Define your varibles and write a system of equations that represents the ticket sales for both Angela and Tyler.
let x=
Let y=
system of equation:
B' Solve system of equation
c' Write answer using a complete sentence.
Answer:
Step-by-step explanation:
Let’s say that the price of an adult ticket is x and a student ticket is y.
we know that 6 adult tickets (6x) and 10 student tickets (10y) equal 122, so 6x+10y=122. Then, 11x+5y=157
6x+10y=122
11x+5y=157
Multiply the first equation by -1/2 and add it to the second to cancel out the y
8x=96
x=12
Plug this back in to equation 2 to find y
132+5y=157
y=5
Checking this with the first equation, it all works out.
The price of an adult ticket for a charity football game is $12, while the price for a student ticket for the same game is $5
If (x + y)^2 = 1 and xy = -4, what is the value of x^2 + y^2?
Answer:
[tex](x + y)^{2} = 1\\xy = -4\\x^{2} + y^{2} \\= x^{2} + 2xy + y^{2} - 2xy \\= (x^{2} + 2xy + y^{2}) - 2xy\\= (x+y)^{2} - 2xy\\= 1 - 2 *(-4) \\= 9[/tex]

In the NBA, any shot made from 22 feet or more from the basket is worth 3 points. How many yards from the basket is that?
Answer:
22/3 yards, roughly 7.33 yards.
Step-by-step explanation:
We know that there is 3 feet in 1 yard.
Given 22 feet, we divide by 3 to find the amount of yards, thus changing the unit.
The exact amount of yards is just 22/3, which you can estimate to 7.33 yds.

Find the perimeter of a regular hexagon with a side of 8 meters
Answer:
8 x 6 = 48
Step-by-step explanation:
Hexagon = 6 sides
8 x 6 = 48
Answer:
48 meters
Step-by-step explanation:
A regular hexagon has six sides, all six sides are the same length. So you have to add 8 meters six times. Or just multiply 6 by 8. So you get 48 meters.

Solve –3d + 5 = 14.
–57
12
–27
–3
Answer:
d = -3
Step-by-step explanation:
–3d + 5 = 14.
Subtract 5 from each side
–3d + 5-5 = 14-5
-3d = 9
Divide each side by -3
-3d/ -3 = 9/-3
d = -3
Answer:
[tex]d = - 3[/tex]
last answer is correct
Step-by-step explanation:
[tex] - 3d + 5 = 14 \\ - 3d = 14 - 5 \\ - 3d = 9 \\ \frac{ - 3d}{ - 3} = \frac{9}{ - 3} \\ d = - 3[/tex]

The dimensions of a rectangle are x+4 and 3x-1. Write an expression to represent the area of the rectangle.
Answer:
9x^4 - 6x^3 + 97x2 - 88x + 16
Step-by-step explanation:
so (x + 4)(x + 4) = x^2 + 8x + 16 is the total length of the rectangle, and
(3x - 1)(3x - 1) = 9x^2 - 6x + 1, if you multiply each other, because Area = length times width, then you get the area.
(9x^2 - 6x + 1)(x^2 + 8x + 16) = 9x^4 + 72x^2 + 144x^2 - 6x^3 - 48x^2 - 96x + x^2 + 8x + 16, and then you add them all together = 9x^4 - 6x^3 + 98x^2 - 96x + 8x + 16 = 9x^4 - 6x^3 + 97x2 - 88x + 16

Please help with this conditional probability question.
Answer:
8/45
Step-by-step explanation:
1. Since the dice has six sides and only two numbers are less than three (2 and 1) that means there is a 4/6 (2/3) chance of them rolling any other number besides 2 and 1. Since in bag two it has the yellow dice.
2. In bag two there are a total of 15 beads (4 yellow and 11 blue) since we want to get the yellow bead that means there is a 4/15 chance of getting a yellow bead.
3. Finally to find the chance of rolling a number greater than 2 and picking a yellow bead you must multiply the numerators and denominators. 2(4) and 3(15) which in turn equals 8/45.
A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream
Answer:
t=4h
Steps below
Step-by-step explanation:
We know:
speed of boat with respect to earth: 13 km
speed of stream with respect to earth: 4 km
13 km/h + 4 km/h = 17 km/h The time to travel 68 km with this speed is thus t = 68 km 17 km h = 4 h
